' Application med nay s,

" This invention' relates to valve construction such as used, lfor example, in gas ranges and is particularly adapted for use in an arrangement wherein the gas valvesare located in a relatively compact cluster while the operating4 handles are located at remote points and at relatively spaced intervals. The stove having such valve and handle arrangement is illustrated in my copending application, Serial :li-345,627, filed March 9,

1929. Brieiy, burner box with which is centrally located within the box, and whichV has gas valves associated therewith for controlling the flow of gas to the respective burners. The handles for operating the valves are placed in the usual location at the front of the stove. The'valves however, are placed relatively close together tially on lines extending transversely to the front of the stove. The poblem presented therefore, is to obtain a fu l opening of vthe valves with a quarter turn of the o erating z5 handle, notwithstanding-the fact t atI the valves are spaced lrelatively close together in 'a compact arrangement, while the stove operating handles are spaced apart and along the front edge of the stove.` A further prob- 80 lem is to provide a satisfactory operating connection between'the handles and valvesl which will permit the valves to be readily operated without the occurrence of a binding action between the operating parts.

One of the objects of the present in ention is to provide a burner control mechanism which enables closely grouped valves within a burner box, to be satisfactorily operated when the handles are disposed along one edge of the box. A further object is to provide a mechanism which shall be simple in construction, and which can be readily installed and thereafter operated to obtain the desired result without the'occu'rrence of objectionable'ifriction of the operating parts.

such mechanism illustrates a agas `and air distributer,`

Referring now to the drawings, Fig. 1 isa plan View of a gas range` embodying my invention; Fig. 2 is a vertical section taken on the line 2-2 in Fig. 1; Fig. 3 is a vertical section taken on the line 8--3 in Fig. 50 2 and Fig. 4 is a section taken on the line 4-4 in Fig. 1. t

My invention is shown in connection with a gas range 10 and whichy has a burner box 11 and an oven box 12. Burners areindicated at 13 within the burner box, and areeach v provided with a 'hollow shank 14 through which a mixture of air and gas may `flow. In the preferred arran ement, the gas distributer 16 is central y located within the box and comprises a hollow casting which is connected to` a supply pipe 15, and also to conduits, 9 which lead into they respective burner Shanks. Air for supportin combustion may be lead into a chamber l; through g5 a conduit 18, which is shown as extending around the supply pipe, and as entering the burner box from the rear of the stove. Gas flowing to the respective burners is controlled by a valve which may, if desired, be built into the body of the distributer.

Th present invention is concerned with a mechanism for operating Valves at points remote from the location of ,the` valve. As applied to a stove, it is concerned with the provision of operating mechanism which permits the use of operating handles at spaced intervals along the front edge of the stove,` notwithstanding the fact that the valves are closely mounted in a compact cluster adja-"SO cent the central part of the burner box. The preferred means for accomplishing this comprises a tapered valve plug 20 which is rotatably mounted within the distributer and which is operatively connected to a valve 86 handle 21 at the front of the stove. To eect such connection, I have shown a rod 22 which extends inwardly and-is provided lat the inner end with a beveled gear '23 which is arranged to mesh with a similar gear 24 upon 00 the plug 20. The outer end of the rod 22 may be supported by an apron which forms part of the burner box while the inner end may be journalled in a bearing block 26. Such block is preferably carried by the plug and in the preferred form is swivelly mounted thereon. Such Swivelled connection .takes the form of threaded pin 27 which extends downwardly from the bea-ring block and engages a correspondingly threaded socket 28 in the plug. The axis of such socket is coincident with the axis of the plug. Thus, each block may be turned to-suit the angle at which the associated rod 22 enters the distributer, as is shown particularly in Fig. 1. When so positioned, it permits a rotation of the plug with reference to the distributerfor controlling the flow of gas to the associated burner. A spring 29 acts in the usual manner to urge the plug into engagement with the valve seat, while a pin 30 in the collar 31 is adapted to engage shoulders 32 and 33 `respectively on the bearing block to limit the degree of plug rotation.

An advantage of my invention is the fact that avbearing block may be turned to the desired degree to accommodate the angle at whichthe valve rod enters the burner box, without requiring specially designed bearing supports on the upper surface of the distributer. A further advantage of my invention is the fact thaty a large number of valves may be compactly arranged in the distributer and yet may be operated in a satisfactory manner from spaced points at the front of the burner box without the presence of a binding action between any of the operating parts.

I claim:

1. In combination, a burner, a valve therefor, said valve including a rotatable member, an operating handle, and means connecting said handle to said member, said means belng swlvelly mounted upon said member.

` 2. In combinatlon, a burner, havlng a gas .passageway leading thereto, a valve in said passageway including a rotatable member, an operating handle therefor, means rotatably connecting theV handle and member, said means including a bearing block swivelly mounted upon the axis of said member.

3. vIn a gas stove, the combination uwith a burner box, of a burner disposed therein, a valve mechanism, comprising a valve body, a valve stem, and a rotatable valve operating member, the valve stem-having a gear rigidly mounted thereon, and having a bearing sleeve swivelly mounted thereon and above the gear, said sleeve providing a bearing for the operating member, and a secondl gear carried by the operating member and in mesh with the first named gear, whereby rotation of the valve operating member causes rotation of said stem.

and member having cooperating shoulders to limit the rotational degree of the member. In testimony whereof, I hereunto aiix my signature.
